Vandalism isn't unheard of at Irvington School, neighbors said Saturday afternoon, but the graffiti that appeared overnight there was unlike anything they'd seen before.

Stetson James, the school facilities manager, said a neighbor called Principal Cynthia Macleod early Saturday to alert her to some bright blue and black markings left on the sides of the school, on playground equipment and on other school structures.

The markings on school grounds at 1320 N.E. Brazee St. included swastikas, racial slurs and the words "white power."

Black spray paint also appeared on two small girls' bicycles locked to a bike stand just feet from the school. On the smaller of the two bikes, a swastika was painted on a basket fastened to the handlebars.

Sgt. Pete Simpson, Portland police spokesman, said there are no suspects. The case will be reviewed by the bureau's bias-crime detectives to look for connections to other incidents. Simpson said he is not aware of a pattern of other tagging cases in the area.

James said tagging does appear at the school occasionally, but this occurrence was more extensive than previous ones.

"I find it very unsettling," said Kevin Jones, who lives across the street from the school.

Jones' children, ages 2 and 3, are too young to attend the elementary school, but he said the graffiti affects more than just students.

"Kids from all over come and play here," he said, "and they have to see this."

Jones noted that some of the graffiti in black paint appeared over New Year's weekend, but the bright blue paint was new.

James said maintenance crews would be out this morning removing the painted messages.
